MACHINE FOR STEFFENING HATS.

SPECIFICATION forming part of Letters Patent No. 426,135, dated April22, 1890.

Application filed August 9, 1889. Serial No. 320,319, (No model.)

To aZZ whom it may concern:

Be it known that we, FRANK J. MURPHY and ANTHONY M. BUNDLE, citizens ofthe United States, residing at Danbury, in the county of Fairfield andState of Connecticut, have invented certain new and useful Improvementsin Machines for Stiifening Hats; and we do hereby declare the followingto be a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to the class of machines described in our formerLetters Patent, Nos. 361,073, dated April 12, 1887, and 396,829, datedJanuary 29, 1889, and has for its object to simplify and improve theconstruction and operation of the machine.

Vith these ends in view we have devised the novel improvements in thedetails of con struction, which we will now describe, refer-- ring bynumbers to the accompanying drawings, forming part of thisspecification, in which- Figure 1 a plan view of the entire machine;Fig. 52, a section on the line 00min Fig. 1, the legs being broken away,showing the spindle, belt-pulley, cone, clutch mechanism, 850., inelevation; Fig. 3, a side elevation of the portion of the machine thatis removed in Fig. 2--that is, the tank, brush-shaft, brush, andadjusting mechanism for said parts 5 Fig. 4:, a section on the line 7 yin Fig. 3, looking toward the right, the tank, however, not being shown;Fig. 5, a detail inverted plan view of the mechanism for determining thethrow of the cone; Fig. 6, a detail sectional view on the line in Fig.a, looking down; and Figs. 7 to 11,inclusive, are detail viewsillustrating the parts of the clampin mechanism detached.

1. denotes the bed of the machine, which is supported by suitable legs 2and is provided with a slot 3, extending through it.

4 denotes a carriage, which is adapted to reciprocate longitudinally ofthe bed, and 5 is a gearwheel journalcd in brackets 6, bolted to theunder side of the bed. This gearwheel is adapted to mesh with a worm 7on a shaft 8, extending longitudinally of the machine. Power is appliedto this shaft by a belt (not shown) passing over a pulley 9, and thecarriage is reciprocated by means of a connecting-rod 10, one end ofwhich is pivoted to the carriage and the other to gearwheel 9, the pointof attachment to said gearwheel being adjustable, so that the throw ofthe carriage may be regulated at will.

In order that the movement of the carriage may be stopped at anyinstant, which would be impossible if depending upon a shifting ofbelts, we provide for disengaging worm 7 from the gear-wheelin a mannerwhich I will now describe.

11 and 12 denote,respectively, therearand front boxes, in which shaft 8is journaled. The rear box is provided with an arm 13, which is pivotedto a bracket 1-lon a cross piece 15, extending between the two rear legsof the machine. It willbe seen that this con-. struction permitsoscillation of the shaft and boxes in the vertical plane. The front box12 is provided with an arm 16, having a slot 17 and at its upper end ahook 18. A bolt 19 passes through slot 17 and through a bracket 11,attached to a cross-piece 15, extending between the two front legs ofthe machine.

20 denotes a strong spring, one end of which is connected to the underside of the bed and the other to hook-1S upon the front box of So theshaft.

21 a foot-lever pivoted to a suitable bracket 22, and 223 is a linkconnecting said foot-lever to box 12. The foot-lever extends outwardbeyond the front of the machine in 8 5 such a position that an operatorstanding at the front of the machine may readily place his foot upon it.It will be seen from Fig. 2 that the action of spring 20 will be to holdthe worm in engagement with gear-wheel 5, 0 so that the carriage willreciprocate continuously until its movement is stopped by the operatorpressing down upon the foot-lever and disconnecting the worm from thegearwheel.

2st denotes the spindle, whichis mounted in boxes 25 on standards 26,extending upward from a turning plate 27, which is secured to thecarriage by a bolt 28. Anti-friction rollers 29 are preferably placed inthe carriage, 10o upon which the turning plate rests, so as to permitsaid plate to oscillate freely. At the forward end of the spindle is acone 30, shown as having a hat-body 31 thereon. The body upon the coneis held in position by clamping-arms 32, pivoted between ears 33 at therear end of the cone and provided with adjustable clamping-surfaces 34.These clamping-surfaces are preferably secured in position by means ofthun1b-screws 35, which pass through slots 36 in the clamping-arms. Theclamping-arms are operated by means of rods 38, the outer ends of whichare threaded to engage hubs 39, which are journaled at the rear ends ofthe arms, turning freely therein. (See Figs. 1 and 11.) The other endsof the rods are pivoted between ears 40 on a ring 41, which is rigidlysecured to a sleeve 42 upon the spindle, the latter being provided witha spline 43, engaging a corresponding groove (not shown) in the sleeve,whereby the latter is held againstrotation independently of the spindle,but is allowed to slide longitudinally thereon. It will be seen that bymeans of the threaded outer ends of the rods and hubs 39 we are enabledto adapt the clamping-surfaces to different thicknesses and qualities ofhat-bodies, and by means of bolts and slots 35 and 36 we are enabled toadjust the clamping-surfaces to different sizes of hat-bodies.

44 is an operating-lever, the central portion of which is bifurcated,and then reunited to permit it to embrace sleeve 42. The lower end ofthis lever is pivoted to ears 45 upon the turning plate, and the upperend is provided with a handle for convenience in operation. I

46 denotes half-collars, which lie in a groove 47 in sleeve 42. Theopposite sides of the central portion of the operating-levers areconnected to these half-collars by bolts or pins 48.

49 denotes a belt-pulley, which is adapted to turn on the spindle, andis provided at its forward end with clutch projections 50.

51 denotes a sleeve on the spindle, which engages a spline 52, wherebyit is held against rotation independently of the spindle, but allowed toslide freely longitudinally thereof. Upon the back face of this sleeveare clutch projections 53, which are adapted to engage projections 50upon the belt-pulley. Sleeve 51 is provided with a groove, (not clearlyshown,) in which are half-collars 54. (See Fig. 2.)

is a lever pivoted to an arm 56, proj ecting backward from the frontbracket 26. The upper end of this lever is bifurcated, and the arms aresecured to half-collars 54 by bolts or pins 57.

53 is a link, one end of which passes through the front bracket 26 andis pivoted to the lower end of lever 55, the front end thereof beingpivoted to operatingdever 44 at a dis tance above its pivotal point toears 45. The operation of this mechanism will be clearly understood fromFig. 2. It will be seen that when operating-lever 44 is moved toward theleft the rear ends of the clamping-arms will be raised, which will pressthe clamping-surfaces down upon a hat-body on the cone, thereby holdingit firmly in position. This movement of the operating-lever will alsodraw the lower end of lever 55 toward the left, which will throw theupper end thereof toward the right, and will force the two sets ofclutch projections 50 and 53 into engagement, as shown in Fig. 2,thereby communieating the rotary movement of belt-pulley 49 to thespindle. The belt by which motion is imparted to belt-pulley 49 and thespindle extends from a suitable main or counter shaft. Neither shaft norbelt is deemed to require illustration. It will be noticed that thebeltpulley is made long enough so that in the longitudinal movements ofthe carriage and parts carried thereby said belt merely hasto slip alongsaid pulley, its actual position being the same at all times.

59 denotes the brush, which is constructed in substantially the samemanner as in our former patents, Nos. 361,073 and 396,829, the essentialprinciple being a hollow shaft or spindle through which the stiffenin gmaterial is supplied to the brush. This brush is fully described andclaimed in our said patent, No. 361,073, and therefore is not thought torequire description in detail, the operation of the brush itself beingthe same as in that patent. In the present machine the brush, shaft, andtank are supported by an extension 60, which is bolted rigidly to thebed.

61 denotes the hollow shaft by which the brush is carried and by whichthe stiffening material is supplied thereto,,said shaft being journaledin boxes 62 upon standards 63.

64 denotes the tank for the stiffening material, which is supported byone of said standards and is connected to the shaft bya suitable union65, a cook 66 being provided to cut off the flow of stiffening materialfrom the brush when not in use. Motion is imparted to shaft. 61 by meansof a belt (not shown) extending over a pulley 67 on said shaft.

It will of course be understood that machines of this class are requiredto operate upon different sizes, qualities, and thicknesses ofhat-bodies. \Ve have, therefore, in our present machine providedadjustments for the various parts to adapt it to all classes of work.

The two principal standards by which shaft 61 is supported are shown asmade integral with an upper plate 68, which is secured to anintermediate plate 69 by set-screws 70,

one of which passes through a curved slot 72 in plate 68, so as topermit said plate, to gether with the shaft and brush, to be oscillatedupon plate 69. This is in order to permit the hollow shaft and the brushto be adjusted in a position other than parallel to the spindle carryingthe cone, so that any desired contact may be secured between the brushand the hat-body upon the cone, it being of course understood that thecones necessarily IOC IIO

vary in size considerably in changing from one style of hat to another.Having secured the necessary adjustment, plate 68 and the parts carriedthereby are rigidly locked to plate 69 by tightening up the set-screws.Under plate 69 is a lower plate 73.

74 denotes grooves or ways in the sides of plate 69, which are engagedby ribs 7 5, which project inward from plates 70, bolted to the sides ofplate 73. Upon the under side of plate 69 is a ing '77, which is engagedby a quick thread (not shown) at the inner end of a rod 78, whichextends to the front of the machine and is provided with a hand-wheel 79for convenience in operation. It will be seen that by turning rod '78through the engagement of the screw-thread thereon with lug '77 plates68 and 69 will be moved toward the right or left, as may be. Thisadjustment enables us to vary the position of the brush longitudinallyto the cone. Upon the under side of plate 73 is a rib 80, which engagesa corresponding groove in the upper side of extension (50. (See Fi 3.)81 is a lug also extending downward from plate 73, which is engaged by aquick thread (not shown) upon the inner end of a rod 82. (See dottedlines in Fig. 4-.) At the outer end of this rod is a hand-wheel S3 forconvenience in operation. By turning this hand-wheel toward the right orleft, as may be, we are enabled to move the lower, intermediate, andupper plates and all the parts carried thereby inward or outwardrelatively to the cone.

M denotes an extension which is rigidly bolted to plate 68. At theforward end of this extension is one of the standards 63, by which thehollow shaft is supported. 85 is a bracket on the under side thereof,which supports the forward end of rod 78. 8G is a dovetail slide fittedin corresponding ways in extension Si and adapted to move transverselyto said extension. A. lug 87, projecting upward from said slide througha slot 88 in the extension, is engaged by a threaded rod 89,whieh isheld against endwise movement, as clearly shown, and is provided with ahand-wheel 90 for convenience in operation.

It will be apparent that in order to stiffen a hat-body it is necessaryto swing the cone with the body thereon inward into contact with thestiffening-brush. )Ve have already explained the construction andarrangement of the cone, spindle, turning plate, the.

91 is an operating handlc rigidly secured to any suitable portion of theturning plate, near the forward portion thereof. When the operatordesired to place a hat-body in contact with the stifl.ening-brush, heseizes this handle and swings the turning plate, cone, 820., into thedesired position. At the forward end of the turning plate ananti-friction roller 92, which is adapted to engage a suitablestop-plate 93 to detern'iine the inward movement of the turning plate,cone, (be. The operative face of this plate is preferably provided.with. a steel strip 94 and with a slight incline 95, the action ofwhich, when roller92 rides down it, is to throw the extreme tip of thehat-body closely against the brush, so that the tip will becomethoroughly stiffened, as is fully explained in our former patent, No.396,829. Stop-plate 93 is connected to slide 86 by means of set-screws96, one of which passes through a curved slot 97 in the stopplate, so asto permit thelatter to oscillate upon the slide. This construction isclearly shown in the inverted plan View Fig. 5. )Vhen it is desired toadjust the stop-plate to change the position of the cone and hat-bodyrelatively to the brush when the cone is thrown to its extreme inwardposition, it is accomplished by turning hand-wheel 90 in eitherdirection, as may be required; and should it be required to change theposition of the stop-plate by oscillating it in the horizontal plane,this may be accomplished by loosening set-screws 96, turning thestop-plate to the desired position, and then looking it by tightening upthe set-screws.

98 denotes a trough placed under the stiffening-brush,which is providedwith a scraperplate 99, with which the bristles of the sizing-brush comein contact in use. The ac tion of this scraper is to remove surplussizing material from the brush, thereby preventing spatter-ing and wasteof the sizing material, and also preventing the sizing ma terial. frombeing deposited upon the hatbody faster than it can be absorbed thereby.A drainage'pipe 100 leads out of the trough, and the surplus sizingmaterial which passes out from the trough is caught in a suitablereceptacle (not shown) placed beneath. This trough is supported by abracket 101, which is rigidly bolted to extension 84:. The trough issecured to the bracket by means of a lug 102, which is pivoted betweenears 103 on the bracket.

104c denotes adjusting-screws, which pass up through the bracket andengage the opposite ends of the trough. By turning these screws upward.or downward, as may be required, the trough may be tilted so as to causeeither end of the scraper-plate to engage more or less positively withthe brush. This arrangement enables us to graduate the quantity ofsizing material applied to different portions of the hat'body. Forinstance, a greater quantity maybe applied at the lower portion of thebody than at the tip, or vice versa.

It will be seen that .by adjusting the trough at an angle the quantityof sizing material deposited upon a hat-body may be made to increase ordecrease gradually in any direction, this being an important feature instiffening certain grades of hats.
